i IMPROVEMENT IN HAV AND COTTON-PRESSES.

The Schedule referred to in these Letters Patent and making part of the lame.

` To all-whom tt may concern Be it known that I, NATHAN CHAPMAN, of Hopedale, Worcester county, in the State of Massachusetts, have invented certain new and useful Improvements in Presses for Cotton, Hay", Sac.; and I hereby dcclare the following to bea full and exact description thereof, reference being had to the accompanying drawing forming part of this specification. The nature or essence `of my invention. consists in the peculiar construction and arrangement of devices` formiugfthe improvements in presses for cotton, hay, and other articles claimed and described in the following specification and represented in the accompanyingdrawing, of which- Figure 1 is an elevation of the back side of the press. v

Figure 2 is an elevation of one end of the press.

In the above-mentioned drawing- .A A are the cross-si1ls on which the bed B of the press is fastened, and to this bed the four posts C C are fastened and connected together by the lowerend bars D D, the upper-end bars E E, the lower-side bars F, and the upper-side bars Gr, .which are. all firmly fastened to the posts C C, making a strong frame, to which the other parts of the press are eitherl fastened or connected.

. In the drawing the doors and side casings of the press are omittedl to show the other parts more clearly, l

i H H are the ends of the press-box, provided with long'slots I for the beam J of the follower to travel in. These ends are fastened to the lower-side bars F and the upper-side bars G, and are connected to' the end bars I) and E by the blocks KK, which hold them firmly in their places; and the upper end of the ends H may be fastened to the bars L L across thc top of the press.

`T he follower-beam J is tted to traverse up and downin the slots I, and is drawnl down, to press a bale, by the links M `M on the ends ofthe beam, connected to the chains N which pass around the vsprocket-wheels P, and pass up between the rollers Q Q, and are connected by ropes It' R, which passV over the pulleys S S to the weights S' S', which draw up the chains as thc follower is drawn down.

' One of the posts C is broken away to show the sprocket-wheel P and the chain running onto it, in

i The journals of the rollers Q Qlturu in a stand, V Q', fastened to the post C.

prevents it from being carried over so as to catchbetween the wheel and that part of the chain drawing down the follower. y

The sprocket-wheels P are cast -with indentations or cavities, whichreceive and fit links of the chains so they cannot slip on the wheels.

The shafts. T T of. the sprocket-wheels turn in the stands T T'fastened'to the bed B, and the stands 'U fastened tothe sills A, as shown in the drawing.

The ratchet-wheels V.V should be cast with the sprocket-wheels I?, or rmly fastened to them, as they l are turned by theratchet-wheels.

To turn the ratchet-wheels and work the press I putthe pin a through the stand T', the lever l), and into the bed B, to form the fulcrum of the lever l), which is connected by the linko to the traversing block (1, which is connected to the shaft of the ratchet-wheel by the link e,- in which said shaft turns freely.

The pin which connects-the links c. and e to block d passes through the pawl f, which catches the teeth of the ratchet-wheel V, when the lever is depressed, to turn the wheel to work the press; and, when the lever b is raised, the pawl f slips over the teeth of the ratchet-wheel to take a new hold and turn the wheel when the lever is depressed.

To hold the ratchet V and prevent it from turning back I pnt a pin, g, through the stand U and pawl h,

and into the bed B for the pawl to vibrate on, and 1 the tail of the pawl serves as a weight to press the pawl against the wheel V and prevent it from turningback when the traversing pawl is liected.

The barj is fastened tothe hars G, and has two pulleys, k k, in it, for the rope l, fastened to the beam J and the weight m, to counterbalance the'chains N and beam J.

The bars L L are perforated, and may be provided with pulleys for the ropes a n from the beam J to the crank-shaft p, which turns in b oxes g on the posts C to wind up the ropes and draw up the beam J.

' The levers b'have a number of holes, r, for the pin in the link c, to vary 'the power of the lever by changing the -pin from one hole to another in the lever.

To work the press, raise the follower and ll the box; then draw the follower down by working the levers b untilthe bale is the size required.

Having described my improvements in presses, VI claim the following:

l. In combination with the traversing block d, the

radial links e, the links c, and pawl j, for turning the ratchet and sprocket-wheels, substantially as described. 1 f

2. I do not claim a lever with its fulcrum on the ratchet-wheel shaft; hnt I do claim the lover b, proing the chain up tothe sprocket-wheel and compel vided with holes, fr, to graduate its power, and wit-h ling it to leave the wheel, substantially as described.

its fnlcrnni in the stand U, in combination with the 5. In combination wit-h a follower, J, drawn down links c, block d, link c, and pawl f, substantially as with single chains, working direct-ly onto the sprockdescribed. et-wheels, the rope, weight, and pulleys, to draw up 3. In combination with the follower J, the sprockthe follower andchains, as described. et-wheel P, arranged in line with the slot I so as to NATHAN CHAPMAN. draw the follower 'straight down the slot without can ting it so as to bind against the sides 'of the slot. Witnesses:

4. In combination with the sprocket-wheel P and J. DENNIS, J r.,

chain N, the arrangement of the rollers Q Q, for hold- CEAS. H. WILLIAMS.
